We stop playing because we grow old;  we grow old because we stop playing.
Even though you're growing up, you should never stop having fun.

The purpose of our lives is to be happy.  Happiness is the secret to all beauty.  There is no path to happiness; happiness is the path.  There is joy in the process of living.  Happiness is found along the way, not at the end of the road.  Take joy in the journey.  Allow yourself to enjoy each happy moment in your life.  Being happy never goes out of style.

Happiness is a journey not a destination; is a direction not a place.  Happiness is not by chance but choice.  You don't find the happy life, you make it.  Nothing will make you happy untill you choose to be happy.  Happiness depends upon ourselves.  No person will make you happy unless you decide to be happy.  Your happiness will not come to you, it can only come from you.

Happiness is state of activity, not out there, it's in you.   It comes from your own action.  Action may not always bring happiness, but there is no happiness without action.  Happiness is an inside job.  Don't assign anyone else that much power over your life.  Being happy doesn't depend on any external conditions, not something ready made.  It is governed by our mental attitude.  Life finds its purpose and fulfilment in the expansion of happiness.  Music was invented to confirm human loneliness.  Life is like a piano.  White keys are happy moments and the black ones are sad moments.  Both keys are played together to give us the sweet music called Life.  Some days I need the music, and some days I need the lyrics.  When you're happy you enjoy the music;  when you're sad you understand the lyrics.  Find what makes your heart sing and create your own

When writing the story of your life.  Don't let anyone else hold the pen.  Don't let the sadness of your past and your fear of the future ruin your happiness.  Live for what today has to offer, not for what yesterday has taken away.  Never expect to find happiness in the same place you lost it.  You cannot protect yourself  from sadness without protecting yourself  from happiness.  Don't let people rent space in your head.  You are the one that possesses the keys to your being.  No one can drive you crazy unless you give them the keys.  Never put the key to your happiness in somebody else's pocket.  The key to being happy is knowing you have the power to choose what to accept and what to let go.  You carry the passport to your own happiness.  For every minute you are angry you lose sixty seconds of happiness.  One joy scatters a hundred griefs.

Happiness is hard to find and easily taken away.  Hope reduces feelings of helplessness, increases happiness, reduces stress, and improves our quality of life.  We can't go back to yesterday and we can't control tomorrow.  Tomorrow is not promised,  today is the tomorrow you worried about yesterday.  There are only two days in the year that nothing can be done, yesterday and tomorrow.  Yesterday is history, tomorrow is a mystery, but today is a gift, that is why they call it  "
The Present".

Life is never easy for those who dream.  Happiness is like a butterfly; the more you chase it, the more it will elude you.  Success is not the key to happiness.  Happiness is the key to success.  The best way to be happy is to make each day happy.  Happiness is not something you postpone for the future, it is something you design for the present.  Do not wait to be happy in the future.  The best time to be happy is always now.  Don't keep waiting for a better tomorrow.  Sometimes later becomes never.

Trying to be happy by accumulating possessions is like trying to satisfy hunger by taping sandwiches all over your body. 
Happiness is not about getting all you want, it is about enjoying all you have.  When you love what you have, you have everything you need.  If  it doesn’t add to your life, it doesn’t belong in your life.  If we concentrate on what we don’t have, we will never, ever have enough.  The happiest of people don't necessarily have the best of everything, they just make the most of everything they have.  Happy people focus on what they have.  Unhappy people focus on what's missing.  Over thinking is the biggest cause of unhappiness.  The happiest people are evaluating and improving themselves.  The unhappy people are usually evaluating and judging others.  The beauty of life does not depend on how happy you are, but how happy others can be because of you.

Happiness is not a goal... it's a by-product of a life well-lived.  Someone to love, something to do, and something to hope for.  If you want to be happy, do not dwell in the past, do not worry about the future, focus on living fully in the present.  The key to happiness is being happy by yourself and for yourself.  Laugh when you can, apologize when you should, and let go of what you can’t change.  Life is very short, so break your silly egos, forgive quickly, believe slowly, love truly, laugh loudly and never avoid anything that makes you smile.

Life does not come with instructions on how to live.  Happiness is a choice.  Don't seek happiness - create it.  Doing what you like is freedom.  Like what you do is happiness.   Don't waste your time in anger, regrets, worries, and grudges.  It's not happiness that brings us gratitude.  It's gratitude that brings us happiness.  Life is too short to be anything but happy.  You only pass through this life once, you don't come back for an encore.  Do whatever makes you happy.  The days aren't coming.  Be so happy that, when other people look at you, they become happy too.

If you want to be happy, be.  It is not how much we have, but how much we enjoy, that makes us happy.  Happiness does not cost you anything.  Don't wait until you are rich to be happy.  Happiness is free.
